I found much the same in my analysis. Liberal women are less likely to marry in the first place and more likely to divorce. They also have far fewer children on average (i.e., liberals are breeding themselves out).

In general, liberals are not as marriage- and child-oriented as are conservatives. Indeed, it seems that liberals (and perhaps, high-IQ people in general) are very choosy about their marriage partners, and are less likely to stick it out if things go awry. But, as I explained in my post, this is result of liberals being predominantly slow-breeders, and are less singly focused on the things that favor reproduction.

Read up on Andrew Gelman and Charles Murray. They generally support the idea that there is a "Large subset of upper-middle-class professionals who follow all the old rules but vote Democrat.

Gelman has found that most of the ideological divide is in the upper class between red and blue states. Specfically, the rich in Republican states are very Republican, whereas the rich in blue states are moderately Democratic. The lower classes in all states are moderately Democratic.

Murray has found that the upper classes still tend to be the ones who get married, stay married, go to church, take part in civics, etc. So the commenter who thought that liberals live conservative lifestyles probably lives in a blue state and spends most of his time with upper-middle class people, which is a biased sample of liberals as a whole.

"The creation myth was the essential bond that held the tribe together. It provided its believers with a unique identity, commanded their fidelity, strengthened order, vouchsafed law, encouraged valor and sacrifice, and offered meaning to the cycles of life and death. No tribe could survive long without the meaning of its existence defined by a creation story. The option was to weaken, dissolve, and die." ~ E.O. Wilson
